Application January 19, 1937, Serial No. 121,246

1 Claim.

The present invention relates to a machine particularly adapted for usein cabinet work, and more particularly for use in the manufacture ofdrawer parts. The cutting and shaping of the several drawer parts asherebefore practiced involves several distinct operations performed bywidely separated machines, one consequence of which is that the work canbe economically performed with new lumber only. This condition obtainsbecause it is more economical to run a long piece of material through asticker and then carry it to another machine for cutting into shortlengths of desired dimensions than to handle a large number of shortpieces of varying lengths.

It is one object of the present invention to provide a machine for thecharacter of work indicated that is so constructed and arranged that oneoperator will be able to perform all of the required operations thereonand that will, therefore, permit the economic use of stock of anylength. I

It is also an object of the invention to provide a machine of thecharacter indicated that will be economical to manufacture, simple inform and construction, durable and compact, and highly efiicient in itspractical application.

In the drawings:

Figure 1 is a plan view of a machine embodying my invention. 7

Figure 2 is a side elevation of the same with a part broken away.

Figure 3 is a perspective illustration of a portion of one of theinclined tables with its fastening means.

Figure 4 is a view on line 4-4 of Figure 1.

In the particular embodiment of the invention herein disclosed I show atl a portion of a supporting bench carryingthe operating motor 2 and twodriven belts 3 and 4. 7

At 5 is shown a base frame seated on the bench and having end members 6and I mounted edgewise thereon and disposed crosswise thereof. Asimilarly arranged member 8 is mounted on the center of thebase frame.These cross members are provided for the support'of four tables arrangedin oppositely inclined pairs and with the pairs at different elevations,consequently they are stepped as at 9, Ill and I I to provide levels l2,13, I4 for one pair of tables and higher levels l5, l6, II for the otherpair of tables. The levels l2 and I4 are uniform in height with theintervening level l3 elevated with respect thereto, and the levels l5and I! are likewise of uniform height with the intervening level I6elevated with respect thereto.

At l3 and 19 are shown one pair of tables hingedly mounted upon oppositesides of member 8 as at 20 and 2E and supported above the level 5 l3 topermit their swinging upwardly on said hinges. These tables are fittedwith fastenings indicated generally at 22, 23 whereby they may besecured in place, and they are also provided with openings as 24, 25through which cutter 10 blades may operate. A gauge member 26 is adjustably mounted on table l8 as at 21, and a guage member 33 is alsoadjustably mounted on table l9 as at 28.

At 29 and 30 are shown a second pair of tables hingedly mounted uponopposite sides of the member 8 as at 3| and 32 and supported above thelevel IE to permit their swinging upwardly on said hinges. The outerends of these tables are supported on levels l5 and ll of members 6 andl, the planes of their top surfaces paralleling those of tables l8 andI9 but elevated with respect thereto whereby material may be fed overthe upper edges of gauges 26 and 33. These tables are fitted withfastenings indicated generally at 34, 35 whereby they may be adjustedsimilarly to tables I8, l9 to secure the desired depth of cut, and theyare also provided with openings as 36, 31 through which cutters mayoperate. A guage member 38 is adjustably mounted on table 29 as at 39,and a gauge member 40 is adjustably mounted on table 36 as at 4!. Asecond gauge member 42 is adjustably mounted on table 30 as at 43 and atright angles to member 40.

At 44 and 45 are shown two shafts mounted in bearings at 46 and 41 onbase frame 5. The shaft 44 carries a cutter 48 operating through opening36 in table 29, and a second cutter 49 operating through opening 24. Theshaft 45 also carries two cutters as 50 and 5| operating throughopenings 25 and 31 in tables l9 and 30 respectively. The shafts 44-45are'driven in the same direction by the motor 2 through the medium ofbelts 3 and 4.

In the present disclosure it may be assumed that the cutter 48 is forcutting the grooves in the side pieces of a drawer, 49 for rounding theedges of the front piece, and 50 for grooving the front to receive theside pieces, 5! being pro vided for cutting a wider groove than 48 whenthe material used requires such wider groove.

It will be apparent from the disclosure that all of the requiredoperations may be performed quickly and easily on this machine, theelevation of the tables 29 and 30 permitting work to be moved thereoveras freely as on the lower tables l8 and [9.

Since tables 29 and 30, and tables [8 and [9 are oppositely inclinedfrom the center member 8 it may be readily understood that work movedalong one table will pass freely over the opposite table which is soplaced as to offer no obstruction. Any cutter head may be changed atwill by swinging the cooperating table upwardly about its hingedmounting.

t is to be understood, of course, that while I have herein shown anddescribed but one specific embodiment of the invention changes in form,construction, and method of assembly and operation may be made withinthe scope of the appended claim.

I claim;

In a wood-working machine, a supporting frame including a stepped memberdisposed crosswise thereof on the central portion thereof, and a pair ofsymmetrically arranged tables associated with each step of said memberand inclined outwardly and downwardly from opposite sides thereof withtheir outer ends supported by said frame, whereby material on any onetable projecting over another table will not encounter any item on saidother table.
